    Going to build a high speed varmint slayer

    I put a deposit down on the new Nucleus custom action made by American Rifle Co. a couple weeks ago for a new build.

    I've had a bunch of Hornady 75 gr AMax bullets setting on the shelf for several years that don't get used. The OAL is too long to shoot out of an AR-15 magazine,and my Savage 12 223 doesn't shoot them as well as it does a 75 gr BTHP bullet.
    For years,I've debated on building a fast twist 22-250 or 22-250 AI to shoot the heavy .224 bullets,but since the the 6.5 Creedmoor has become a main stream commercial cartridge there have been several people wildcatting it with very good results. So I decided to build a 22 Creedmoor,and have the performance of the 22-250 AI without having to fire form the cases,or buy custom dies. I can use my 6.5 Creedmoor dies,and just swap out the neck bushings.
    Plus,AlphaMunitions is going to produce 22 Creedmoor head stamped brass,so I don't have to neck down any brass.

    As with most overbore cartridges,barrel life is pretty short- 1000 to 1200 rounds before you loose accuracy,so I won't be putting a top shelf barrel on it.
    Very few barrel makers have a reamer for it,but I talked with John at Ragged Hole barrels and for $50 more than the price of the barrel,They will buy a reamer. That saves me over $100 since I don't have to buy one. They use Wilson Arms & X-caliber blanks,and I'll probably go with the Wilson Arms for this rifle. I shouldn't have any problem getting it to shoot 1/2 moa or better with my loads.

    I'll loose a little velocity since I will go with a 20" tube,but I hang a 9" suppressor off the end. I should still get around 3200+/- fps with the 75 gr AMax out of it!

    That's as far as I've got on my plans for this rifle,I have plenty of time to decide/find a stock or chassis - probably a used one,the trigger,and the optics.

    That’s a fast bullet! Is it comparable to the 223 Valkyrie?

    HaHa, The 22 Creedmoor case holds around 10-12 more grains of powder over the 6.8 SPC case of the 224 Valkyrie.

    I've just about decided to get a Manners EH5 stock for this project. I have always wanted a Manners stock, and it will be a good match for this rifle, a lighter weight varmint hunting weight rifle.
    I'm just waiting on an email about some questions I have about it, then I'll make my decision.

    What is the diameter of the barrel? Are you using a lighter weight profile on it too?

    It's a light varmint contour, so it's a little smaller diameter but since I'll chop it down to 20" you won't notice the difference.
